Pieter:

I'm using well water in two planted tanks here. GH is pretty much off the
scale of my test kit, and KH runs around 5 or so.  I've not had problems
that I can -definitely- attribute to the hardness of the water, and I can
grow a pretty wide range of plants. I've never had a problem with any crypts
I've tried.  The only plant that really does not seem to like my water is
cabomba.
